Privacy at DataWise
We collect only what you send us, we use it only to answer you, and we never sell it, pool it, or add you to a mailing list.
The short answer
We collect only what you send us, we use it only to answer you, and we never sell it, pool it, or add you to a mailing list. This page explains exactly what that means for the two places on this site where anything is collected: the contact form and AI Mode.
Who we are
DataWise Data Science (Dan Malka) is a boutique data-science consultancy based in Israel. For any question about your data, or to exercise the rights below, write to hello@datawiseds.com. The founder reads it personally.
The contact form
When you write to us through the form, you send your name, your email, an optional company name, and a description of your problem. We use it for one thing: to reply and, if it makes sense, to scope your project. The message is delivered to our inbox through EmailJS, our email-delivery provider. We do not store it in any database, we do not build a marketing list from it, and we do not share it. This is the same commitment as the confidentiality note on our contact page: no mailing lists, no sharing, and no naming you anywhere without your written permission.
AI Mode
AI Mode answers your questions using only the content published on this site. When you ask something, your question is sent to our answering service and to Cerebras, the AI provider that generates the answer; the relevant passages are matched on our own edge, not by a third party. We designed it to keep as little as possible: your questions and your IP address are never stored on our servers, and conversations are ephemeral, so nothing is kept after the session. For operations we log only technical events (which passages were retrieved, response times, and token usage), never the content of what you asked, and the conversation itself lives only in your browser’s session storage. An invisible bot check (Cloudflare Turnstile) runs on your first message to keep the service available. AI answers can be imperfect; verify anything critical with us directly.
Booking hand-off in AI Mode
AI Mode has one optional step that shares anything, and it is off unless you turn it on. When you choose to book a scoping call from inside AI Mode, you see a checkbox that is unchecked by default. Only if you tick it do we pass along a short snapshot to help us prepare for the call: the questions you typed in that session, the page you were on, and your language, and nothing else. The checkbox shows you the exact list before you continue. We never include the answers you were given, your IP address, your name, or anything you typed into any other form. If you leave the box unchecked and simply book the call, nothing from the conversation is shared. Today this snapshot stays on your own device; when our internal scheduling system is ready to receive it, the same opt-in and the same questions-only limit will still apply, and this page will say so.
What we never do
Your data stays for your purpose only. Nothing is sold, nothing is pooled, and nothing you send is used to train or improve anyone’s models.
Cookies and storage
This site sets no cookies and runs no analytics or advertising trackers. AI Mode uses your browser’s temporary session storage to hold a bot-verification token that lives only until you close the tab and never leaves your browser. If we ever add analytics, we will update this page and, for visitors in the EU, ask for your consent first.
Sub-processors
A short list of the services that may handle your data on our behalf: EmailJS (delivers contact-form messages), Cerebras (generates AI Mode answers), Cloudflare (invisible bot protection for AI Mode), and our hosting provider. Some are outside Israel and the EU; where your data crosses borders it does so only to provide these functions, under those providers’ own safeguards.
Your rights
Under Israel’s Privacy Protection Law and, for visitors in the EU, the GDPR, you can ask us what data of yours we hold, ask us to correct it, or ask us to delete it. Because we keep so little, this is usually a one-email matter. Write to hello@datawiseds.com.
How long we keep things
Contact-form emails stay in our inbox for as long as the conversation is useful, and you can ask us to delete them at any time. AI Mode keeps nothing.
